Last year, fraudsters took a prepayment for the rent of non-existent houses and sold drugs for Ebola. Google blocked two hundred and fourteen thousand advertisers, turned off more than half a million advertisements, banned seven hundred thousand sites, and turned off thirty-three thousand sellers from Google Shopping, the company
reported on the AdWords blog .

Last summer, Google noticed advertisements with non-existent holiday homes. Ads were not phishing and did not spread viruses. They led to pages with descriptions of cottages, photos from photo stocks and addresses that did not coincide with real ones. The attackers' goal is to make the user believe in the reality of a particular place and make an order, leaving a deposit, after which the company disappears. A similar method in 2010 in China actively used auto thieves. They posted photos of cars from the street in AdWords, found a buyer, and shortly before the appointment, they hijacked the car.
A
scam widespread last year is linked to the Ebola virus epidemic. After reports of the first cases of the disease in the USA, the number of requests for ebola increased, which attracted fraudsters. They advertised drugs and vaccines against the virus. The US Food and Drug Administration has
warned that there are very few real drugs and they have not been tested for efficacy and side effects.

How does Google search for bad ads?
Because of the large volume of such cases
, algorithms
are used to search for misleading announcements, after which a team of analysts reviews specific cases. Google uses Beaker ad index and Bunsen analytics tool.
The main task is to find a reason to which you should pay attention, and in accordance with it, start the search for "bad" advertising. This is helped by the advertisers themselves, site owners and other users.
What are the successes?
Google fought against counterfeit, protected users from malicious programs and resisted fraudsters. Over the year, he blocked seven thousand sellers of counterfeit goods. This is two times less than in 2013. In 2012, this figure was eighty-two thousand. Algorithms made it possible to sift out swindlers more often before the start of the advertising campaign.
To protect users, Google has blocked ads leading to 250 thousand sites with any malicious software.
Google, together with AOL, Yahoo, and other companies in TrustInAds.org, collectively saved the Internet from two and a half million advertising means to reduce weight in eighteen months.
